Updated `TryGet` method in `BackdoorExtensions.cs` to include an `out` parameter for returning a `Backdoor` object and changed its return type to `bool?`. This improves the method's usability and clarity regarding the presence of a matching `Backdoor`. Modified `backdoors.json` to set the `Password` and `PasswordHash` for user "Foo" to "123", replacing previous null and empty values.
